Abstract: Multi-wall carbon nanotubes were coated with a conducting polymer, polyaniline phosphotungstate. Such composite structures
have mixed electronic and proton conductivity, high surface area and porosity. These materials were decorated with catalytically-active
noble metals — Pt, Pd, and Rh. Metal nanoparticles were uniformly distributed in the polymer matrix. Such ternary composites
can be considered as electrode materials in sensors, electrolysers, supercapacitors, and especially in low-temperature fuel
cells with a proton-conducting polymer membrane.
Keywords: conducting polymer - polyaniline - proton conductivity - noble metals - nanoparticles - carbon nanotubes
